Bitnami Kafka for Kibernetes - java.net.UnknownHostException: kafka-0.kafka-headless.kafka.svc.cluster.local

我在我的k8集群上安装了bitnami kafka。但我一直在kafka-o日志中看到错误java.net.UnknownHostException: kafka-0.kafka-headless.kafka.svc.cluster.local。
我登录到pod (kafka-o)并运行nslookup查找kafka-0.kafka-headless.kafka.svc.cluster.local，但IP得到了解决，没有出现任何问题
root@kafka-0:/# nslookup kafka-0.kafka-headless.kafka.svc.cluster.local

尝试编辑clusterDomain参数，在部署图表时将其设置为mosip02.local而不是cluster.local
